What are some tips for visualizing data in RMarkdown?

To effectively visualize data in RMarkdown, consider using ggplot2 for advanced graphics, and ensure your code is well-commented.

Can you give me an example of a simple ggplot2 chart?

Sure! Here's a basic example:

library(ggplot2)

data(mpg)

ggplot(mpg, aes(x=displ, y=hwy)) +
  geom_point() +
  labs(title='Engine Displacement vs Highway MPG')

This creates a scatter plot of engine displacement against highway miles per gallon.

How can I customize the colors in my ggplot?

You can customize colors using the scale_color_manual() function. For example:

ggplot(mpg, aes(x=displ, y=hwy, color=class)) +
  geom_point() +
  scale_color_manual(values=c('red', 'blue', 'green'))

This will set specific colors for different classes.

What about adding titles and labels?

You can add titles and labels using the labs() function. For example:

labs(title='My Plot Title', x='Displacement', y='Highway MPG')
